title: Synthesis and pharmacological evaluation of N'-morpholinomethylurea derivatives with platelet antiaggregant activity.
abstract: In the attempt to prolong and stabilize the known antiaggregant activity of morpholinomethylurea (MMU) derivatives were prepared with carboxylic acids possessing antiaggregant, anti-inflammatory or hypolipemic activity. The results of the experiments showed the important anti-aggregant and hypolipemic activity of N-2-(p-chlorophenoxy)-isobutyryl-N'-morpholinomethylurea (plafibride, ITA 104). The results obtained seem to indicate that the activity of these new N-acyl-N'-MMU is due initially to the molecule per se although it cannot be totally ruled out that part of the pharmacodynamic effect of the MMU may depend on a prodrug-like behaviour.
